Navigate through a desolate, urban cityscape shrouded in an eerie green fog, where a mysterious contagion threatens to engulf everything in its path. This highly volatile 5x5 grid slot, offering 40 fixed paylines, immerses players in a dark atmosphere with its detailed, apocalyptic visuals and suspenseful audio. The core gameplay revolves around the groundbreaking Infective Wild feature: when a special wild symbol lands, it immediately "infects" all adjacent symbols of the same type, transforming them into additional wilds to significantly boost winning combinations. Landing three or more brain scatter symbols activates the lucrative Free Spins round, where the infectious wilds become even more prevalent, promising thrilling, high-potential payouts and a max win of 5,000x the bet.
